Title: Molecularly Mixed Composite Membranes for Advanced Separation Processes

Abstract

Porous organic cages (POCs) are individual soluble, porous molecules. Additionally, when fabricated into mixed-matrix membranes (MMMs), the soluble POC molecules have the potential to exhibit intimate molecular-level mixing with the polymer matrix. POCs have only recently been incorporated into mixed matrix membrane materials, but this process has not yet resulted in significant improvements of membrane performance. Now, vertex-functionalized amorphous scrambled porous organic cages (ASPOCs) have been utilized as membrane performance enhancers and the amorphous ASPOC mixtures are observed to distribute throughout the matrix without any indication of particle formation or agglomeration, creating unique, molecularly mixed composite membranes. Overall, the molecularly mixed composite membrane provide significant increases in both membrane permeability and selectivity, offering new avenues for creation of membranes with unique properties in industrially relevant separations.

Molecular Blends of Methylated-Poly(ethylenimine) and Amorphous Porous Organic Cages for SO₂ Adsorption

Journal Article Zhu, Guanghui ; Carrillo, Jan-Michael Y. ; Sujan, Achintya ; ... - Journal of Materials Chemistry. A

Porous organic cages (POCs) are emerging porous materials that exhibit intriguing properties in the areas of self-assembly, host-guest interaction, and solution processability. Here in this work, we explore the applicability of POCs as molecular porous supports for polymeric amines. We find that primary amines in poly(ethylenimine) (PEI) can undergo metathesis with the imine bonds present in POCs, resulting in non-porous products. This problem can be overcome by transforming the primary amines in PEI to tertiary amines via methylation. The methylated PEI (mPEI) forms homogeneous composites with amorphous scrambled porous organic cages (ASPOCs) without undesired reactions or phase separation. The microscopicmore »« less

Molecularly Mixed Composite Membranes: Challenges and Opportunities

Journal Article Zhu, Guanghui ; O'Nolan, Daniel ; Lively, Ryan P. - Chemistry - A European Journal

The fabrication of porous molecules, such as metal–organic polyhedra (MOPs), porous organic cages (POCs) and others, has given rise to the potential for creating “solid solutions” of molecular fillers and polymers. Such solid solutions circumvent longstanding interface issues associated with mixed matrix membranes (MMMs), and are referred to as molecularly mixed composite membranes (MMCMs) to distinguish them from traditional two-phase MMMs. Early investigations of MMCMs highlight the advantages of solid solutions over MMMs, including dispersion of the filler, anti-plasticization of the polymer network, and removal of deleterious interfacial issues. However, the exact microscopic structure as well as the transport modalitymore »« less

Design of enhanced porous organic cage solubility in Type 2 porous liquids

Journal Article Rimsza, Jessica ; Nenoff, Tina M. - Journal of Molecular Liquids

Decreasing cost of technologies for direct air capture of carbon can be achieved through the design of new materials with high CO₂ selectivity that can be incorporated into existing industrial processes. An emerging class of materials for these applications are porous liquids (PLs). PLs are mixtures of porous hosts and solvents with intrinsic porosity due to steric exclusion of solvent from inside the porous host. It is currently unknown how solvent -porous host interactions affect porous host solubility in the bulk solvent. Here, in this study, density functional theory simulations were used to investigate interactions between nine solvents and amore »« less

In Silico Prediction of Structural Properties of a Racemic Porous Organic Cage Crystal

Journal Article Liu, Yang ; Zhu, Guanghui ; You, Wenqin ; ... - Journal of Physical Chemistry. C

Porous organic cage (POC) solids are porous materials made up of individual porous molecules held together by noncovalent forces. While many examples of POCs have been made in homochiral forms (i.e., crystals in which every molecule has the same chirality), crystallization of POCs that contain mixtures of chiral molecules can also yield useful properties. For example, our previous work has demonstrated that a POC crystal [cage crystal 3 (CC3)-racemic] synthesized using a racemic mixture of diaminocyclohexane has improved sorption properties and stability than a similar POC crystal synthesized with homochiral diaminocyclohexane. The main purpose of this paper is to predictmore »« less
